3M™ floor edger discs offer great productivity and value on bare wood or nongummy finishes. They cut faster, run cooler and last longer than conventional discs. The discs feature the familiar purple Regalite™ mineral, and tough paper backing. Regalite Paper discs run cool, cut faster and last longer than conventional discs. The specially engineered grit provides a consistent, uniform cut throughout its life, ensuring a professonal finish every time. Regalite discs save time, boosting productivity. The trademarked purple abrasive is the standard for excellence in floor sanding discs. Initial sanding with a coarse grit, grade 36 abrasive flattens the wood and removes scratches and gouges, but leaves "peaks and valleys".
